5:58 Making R1Mohm 1W with R 1Mohm 1/4W
Carbon film resistors are typically marketed for between 1/6 W to 5 W at 70 °C. Resistance is available between 1 ohm to 10 MOhm. Carbon film resistors can operate at temperatures between -55°C to 155°C. It has a maximum working voltage of 200 to 600 v.
What does the watt rating of a resistor mean?
The Watt number (W) on the resistor is intended to provide information about its power capability. When a resistor is installed in a particular circuit, it will produce a voltage and current flowing. The voltage and current flowing in these resistors form power, and this is called power dissipation.
Explain what is a resistor and its units?
Resistors, also known as barriers, are passive electronic components that function to inhibit and regulate the amount of electric current in an electronic circuit. The unit of value for resistors or resistance is ohms.
What is a resistor used for and what is its symbol unit?
Answer: Resistor is a basic electronic component that is always used in every electronic circuit because it can function as a regulator or to limit the amount of current flowing in a circuit. ... The unit of resistance of a resistor is called Ohm with the symbol (Omega)
Fixed resistor (Fix Resistor) is a resistor whose resistance value can not be adjusted (fixed), while variable resistor is a resistor whose resistance value can be adjusted. Of these two types of resistors, there are several variants that are adapted to the purpose or function of their use.
What material are resistors made of?
Resistors that have been painted with a color code according to the resistance value. The resistive element is made from a mixture of carbon powder and an insulating material (usually ceramic). Resin is used to bond the mixture. The resistance is determined by the ratio of the carbon powder to the insulating material.
